*** This bug is a duplicate of bug 202089 ***
https://bugs.launchpad.net/bugs/202089
I really don't think this is duplicate of #202089 because this happens
also in lubuntu which doesn't use pulseaudio.
My tests show that this happens on the latest lubuntu 13.10 amd64.
I have a HPCompaq 6720s laptop with the following sound card:
ubuntu@ubuntu:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: AD198x Analog [AD198x Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
ubuntu@ubuntu:~$
After resume this is what I do in order to get the sound back:
1. kill all processes keeping devices in /dev/snd/ open. You can find
them by typing:
lsof /dev/snd/*
After that you use the kill command on them
2. force an alsa reload. You do this with the following command:
sudo alsa force-reload
3. IF NEEDED: You start again the programs you previously killed

6) Restarting ALSA (sudo /etc/init.d/alsa-utils start ) doesn't change
the issue

doesn't help either
